Portable three-phase power quality analyzer
Product Overview
The portable three-phase power quality analyzer is a special portable product for detecting and analyzing the operating quality of the power grid. It can provide harmonic analysis and power quality analysis in power operation. It is also equipped with a large-capacity memory, which can conduct long-term data collection and monitoring of power grid operation. It is also equipped with application software to upload the collected data to the computer to facilitate various operations. analyze.
Design Features
◆ Color touch screen display for easy operation.
◆ High-performance lithium battery provides power for a long time.
◆ Chinese menu operation, easy to learn.
◆ Modular structure, reasonable design and reliable operation.
◆ Complete three-phase troubleshooting tool.

Product functions
◆Voltage, current and frequency
It can measure three-phase voltage, neutral line voltage, three-phase current, neutral line current frequency, etc.
◆Harmonic Measurement
Can measure harmonics down to the sub-harmonic. The measurement results include the amplitude of each harmonic voltage, harmonic current, the total distortion of the voltage harmonics, and the total distortion rate of each voltage harmonic/current. The harmonic content rate can display the harmonic spectrum diagram.
◆Power measurement
It can measure three-phase apparent power, active power, reactive power, power factor, three-phase electric energy, etc.
◆Three-phase unbalance measurement
Can measure three-phase voltage unbalance and positive sequence negative sequence zero sequence voltage. Three-phase current unbalance and positive sequence negative sequence zero sequence current can display voltage vector diagram and current. Vector illustration.
◆Surge current
At least multiple surge current events can be recorded.
◆Flicker/Flicker
Measurement of short-term flicker and long-term flicker.
◆Swell/sag
Can record voltage swell and sag events, up to 1 event can be recorded.
◆Monitoring and recording
Basic steady-state power quality parameters can be recorded for a long time, and the recording time interval is adjustable from seconds to minutes.
◆Digital oscilloscope
Can be used to view voltage/current signal waveforms.
